If you're relatively new to Ae this is not an easy job. It's too involved to describe in detail here. Basically you'll be hand animating masks or shape layer paths. Pen drawn shape paths have a more complex organisational structure than basic masks on a solid, but offer some 'path modifier' functions that you might want to use. The basic method would be similar for a mask or shape path - keyframe the path over time. Mask / shape animation is, unfortunately, not one of Ae's greatest strengths. These are some of the topics you'll need to investigate and learn about. Google is your friend. pasting paths / multiple paths from Ai into Ae mask interpolation set first vertex rotobezier v bezier paths maintaining constant vertex count shape layers and path modifiers One general tip: Look at your fully grown tree illustration - you might be better off creating this by overlapping 3 shapes - the main trunk, and the two individual branch shapes. You can then deal with morphing these individually - rather than trying to do everything in one big shape. The same is true for the seed and shoot - two objects. This is a classic rotoscoping technique and one which may help you achieve a smoother final animation.
